For fast, reliable HVAC service in Oak Lawn, call Captain Cool Heating & Air at (815) 662-0339.

Oak Lawn, on the southwest side near Midway, is largely mid-century brick ranches, raised ranches and bungalows. Many of those homes are now on their second or third furnace and AC, and original ductwork is often undersized for today’s equipment, so we check airflow and duct sizing on every replacement before recommending a system.
